A method and system is provided for associating private branch exchange (PBX) equipment with a remote access device over a packet network. The remote access device can be connected to a number of communication devices suitable for processing voice or data. The PBX equipment receives a request to initiate communication from the communication device over a signaling virtual channel provisioned from the packet network, provisions a communication virtual channel from the packet based network to carry communication information provided by the communication device, transmits control signals over the signaling virtual channel to control the timing and transfer of information associated with the communication device and the corresponding remote access device, exchanges communication information over the communication virtual channel, and transmits control signals over the signaling virtual channel that terminates the communication virtual channel and relinquishes resources provisioned from the packet network.
